“…The Second Harmonic Generation (SHG) response of these two compounds was estimated by theoretical calculations and compared to experimental measurements of powdered samples. Finally, in order to test the behavior of such compounds under thermal neutron irradiation, we preliminarily exposed powdered LiM 2 B to the thermal neutron radiation field of the E_LiBANS facility [5] at the Physics Department of Torino.…”

In this work, we synthetized and characterized new crystalline materials with theranostic properties, i.e., they can be used both as bio-sensors and for “drug delivery”. The two solid crystalline compounds studied are Metal Organic Frameworks and have formulas Li[(C6H12O6)2B]·2H2O and Li[(C4H2O6)2B]·5.5H2O. They can be synthetized both with natural isotopes of Li and B or with 6Li and 10B isotopes, that can be explored for Neutron Capture Therapy (NCT) for anti-cancer treatment. The presence of chiral organic molecules, such as mannitol and tartaric acid, provides the NLO property to the crystals and thus their capability to generate the Second Harmonic, which is useful for applications as bio-sensors. The two compounds were characterized with X-ray Diffraction and the Second Harmonic Generation (SHG) responses were estimated by theoretical calculations, and the results were compared with experimental measurements of powdered samples. In order to test the behavior of such compounds under thermal neutron irradiation, we preliminary exposed one of the two compounds in the e_LiBANS facility at the Torino Physics Department. Preliminary results are reported.

“…The Torino facility exploits the bremsstrahlung gammas produced by the conversion of the electron beam, produced by an ELEKTA SL 18 MeV Linac, on a thin tungsten target [6]. The high energy gammas can then be used to produce neutrons through (γ, n) reaction on a high-Z material as lead.…”

“…The root technology, upon which the new diagnostics are based, is the Thermal Neutron Rate Detector (TNRD) developed by the group under previous projects [3]. The "TNRD technology" is characterized by the differential readout of an assembly of two silicon detectors where a thin layer of 6 LiF is deposited on one of the two detectors while the other operates "bare". The 6 LiF has an extremely high absorption cross section for thermal neutrons.…”

The e\_LiBANS project aims at creating accelerator based compact neutron facilities for diverse interdisciplinary applications. After the successful setting up and characterization of a thermal neutron source based on a medical electron LINAC, a similar assembly for epithermal neutrons has been developed. The project is based on an Elekta 18 MV LINAC coupled with a photoconverter-moderator system which deploys the (γ,n) photonuclear reaction to convert a bremsstrahlung photon beam into a neutron field. This communication describes the development of novel diagnostics to qualify the thermal and epithermal neutron fields that have been produced. In particular, a proof of concept for the use of silicon carbide photodiodes as thermal neutron rate detector is presented.
